| UPA00363 | L-leucine degradation~Degradation of L-leucine, one of the three main branched chain amino-acids (BCAAs), along with L-valine and L-isoleucine. In plants, branched-chain amino-acids are synthesized in chloroplasts, whereas the degradation takes place in mitochondria. | Both - {{t,f}} | None - {{∅},{t}} | Ambiguous |  |
